About the original hardware This library is based on the Tube Harmonics function of a Modern German Tube Compressor which is loved by many for its versatility and audio quality with the musicality and user-friendliness that this company's units stand for. It finds its application in Mastering, Mixing and Recording. Discrete, very high performance gain cells were developed for this compressor and are used instead of the usual VCAs. This compressor is the first product to use them. They ensure the highest level of musicality and clarity in signal processing and demonstrate significantly improved distortion values over VCAs. The adjustable tube saturation of the output stages combined with automatic output level adjustment can produce tube sound effects that range from the delicate to the raucous.
